OCTG Tubing

KPE tubing is the conduit used to transport crude oil or natural gas from the producing formations to the field surface facilities for processing after drilling is completed. During the extraction process, the OCTG tubing must withstand the pressure and it must be adequately strong to resist loads and deformations associated with production and workovers.

In addition, tubing generally is sized to satisfy the expected rates of production of oil and gas. That is because if tubing is too large, we will have an economic impact beyond the cost of tubing oil and gas itself, however, if API tubing is too small, it will restrict the production of oil or gas, and if things continue this way it will impact subsequent economic performance of the well. Generally, tubing is manufactured in the same way as casing, except an additional process known as “upsetting” which is applied to thicken the pipes.

In our company KPE, outside diameter of tubing is from 1.660” to 4 1/2” (42.16 mm to 114.3 mm); wall thickness is from 2.3 PPF to 26.10 PPF (3.57 mm to 9.52 mm). Based on the standard of API 5 CT, ISO 11960, GOST, and their steel grade are from H 40, J 55, N 80, N 80 Q, L 80, L 80-1, L 80-9 Cr, L 80-13 Cr, P 110 etc. As you know the length range is R1 (6.10-7.32 M), R2 (8.53-9.75 M), R3 (11.58-12.8 M), R2 is used frequently.

Besides EU and NU end type could be provided byKPE , and premiums thread type are also available.
